The device “Profil-1” is intended for measurement of internal surface profiles of stators of the bottom hole motors (BHM). When rotation of the measuring unit of the device around the fixed axis a contactless measurement (by means of the laser) of distances to the surface of the stator and a measurement of rotation angles of the measuring unit (planes of measurements) in relation to starting position are carried out.
